Endoleak Type Origin of the leak

I Inadeguate seal at the proximal (IA) or distal (IB) end of the stent graft

II Retrograde flow from the inferior mesenteric artery, lumbar arteries, others collateral

vessels of the aneurysm sac

III Component disconnection (IIIa) or fabric disruption (IIIb)

IV Graft material porosity

V Endotension: increase of the pressure without any visible evidence of blood in the

aneurysm sac

Conversion to open repair after endografting for AAA:A review of causes, incidence, results and surgical techniques of reconstruction

Moulakakis KD et al.

J Endovasc Ther 2010; 17: 694-702

Early Conversion Late Conversion

Incidence (mean) 0.3%-5.9% (1.5%) 0.4% - 22% (1.9%)

Mortality rate (mean) 0 – 28.5% (12.4%) 0 – 20% (10%)

Predictive factor Female gender Type I/II endoleak, graft

migration, kinking

Causes 1.Technical failure on deployment- severe iliac arteries

- inability to catheterize controlateral limb

-incorrect deployment of the stent-grafte

- insufficient connection of the variuos parts

2. Inappropriate stent graft placement- graft migration

- type I endoleak

- high deployment with renal arteries coverage

3. Vessel rupture- iliac arteries

- abdominal aorta

4. Graft thrombosis

1. Aneurysm expansion- type I/II/III endoleak

- stent-graft migration

2. Persistent endoleak

3. Endograft thrombosis

4. Graft infection

Results of endovascular conversions with F/BEVAR Endograft


Conclusions

• Type IA EL happens when there is an inadequate seal at the proximal end of stent-graft

• Type IA EL is associated with an increase of sac pressure and risk of AAA rupture

• Type I A EL should be treated promptly

• Re-intervention to achieve a seal, primarily by endovascular means, is recommended

• The endovascular choice should be based on appropriate landing zone to achieve a seal
